WRAPPER-CUTTING AND REGISTERING APPARATUS..

. Specification of Letters Patent.

' Patented May 21, 1907.

Original application filed April 3, 1905, Serial No. 253,517. Dividedand this application filed November 16, 1905.

- Serial No. 287.744- 1 To all whom itmwy concern:

' Be it known that I, Janus HENRY BRADY, a citizen of the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented a new and useful Mapper-(Puttmg and RegisteringApparatus, of which the following is a specification.

This invention relates to means for cutting.

printed wrappers from a web used in wrap ping i'nachincs and registeringthe printed label portion upon the article wrapped therein. l The web issevered while in motion by 'cutting devices whose operation iscontrolled in the accompanying drawings is one which experience hasdemonstrated to be practical and efficient but changes in the details ofstructure and arrangement may, no doubt,-

be devised by those skilled in such matters without departing from theprinciples of the invention. Figure 1 is a longitudinal sectionaldiagrammatic view; Fig. 2, a transverse detail section-showing the websevering cutter and its trigger; Fig. 3, a bottom plan view showingelectrical contacts that control an electric circuit that determines themoment of actuation of the cutter; Fig. 4, a longitudi- .nal detailsection, on a larger scale than Fig. 1, showing the electrical contactdevices; Fig. 5, Fig. 6, an enlarged detail view of the electric contactdevices.

2, indicates a horizontal base plate upon which-is mounted a reciprocalcarriage 3, by means of guide-shoes 51 grooved to receive the edges oftho-plate 2. y The side bars of carriage 3 are rigidly connected at eachend by cross-piece ll. The rightdnind end of Fig. l is regarded as thefront of the machine for the purpose of thisdescription.

The figures in the drawings illustrate my invention as embodied in. amachine for wrapping cakes of chewinggum, a full description of whichwill be found in the application above referred to.

To the rear cross-piece 14; is secured a a plan view'of the label weband cake-ejecting bar 15, adapted to push the bottom cake from astationary hopper 50. When carriage 3 moves forward bar 15 pushes thebottom cake in hopper 50 forward under springs 55 and 56 until the rearedge of the cake drops in'front of a shoulder formed by an abutmentplate 17 attached to the base plate and constituting the bottom of theho ppel, V

9 represents a web of waxed paper, and S a printed label web, which aretogether drawn forward, one superimposed upon the other, under thebase-plate, through the contact devices, and upward through a diagonalslot 65, in the base-plate upon the upper face of which they lie. In thebase-plate in front of springs 55 and 56, is a spring 57, acting to.elevate the free ends of webs 8 and 9-. When the lowest article or cakein the hopper is pushed forward, springs 55 and 56 press it upon theweb, the end of which, extending beyond it, is slightly elevated byspring 57 (Fig. 1).

The laliel web 8 is formed with openings, or breaks in its uniformcontinuity,'shown, in.this instance, as perforations 64 ,(or'slits 19and 10) (Fig. 5), arranged mid-way between the printed labels. If a slitlike that illustrated at 10 is used, the transverse out thereof ispreferably disposed centrally between the labels. The exact location ofthe openings in the web depends upon the adjustment of the devices.

Y Electriccontact devices (Figs. 1, 3,4,5) are secured to the under faceof the base plate. The. waxed web 9 (Fig. 4) passes above, and theperforated label web 8 below, a separating plate. An insulated contactspring 61, provided with an upturned 'tacts 5?) and 60, until spring 61,enters a perforation or slit, and so lifts contact piece 59 againstcontact 60 closing an electric circuit.

A wrapper-folding shoe 18, having apresser spring 68, in front and anauxiliary presser spring 69, is ca led at the rear end of a shoearm 16,secured to and reci roosting with the front cross-piece is (notillustrated) oi oarriege 3. in the basc-plate eshort distance in frontoi spring 57, there is e slot 66 adapted to receive the cutting edges ofa cutter 67, pivoted on a shaft 1. on one side of base-plate 2, andurged downward by e strong spring 6. Just above the cutter is a trigger12, (having it spring 4 applied to it) pivoted on a stud 13, and havingoneend notched to hold the free end of the'cutter, end its opposite endprovided with anermeture for anelectro mag: net 1. A cord passingover aguide ullcy and through the eye of c link csrrie by a stand ard 5 ontheba-ss plate has one end attached to cutter 67 near itsnpper edge, andits other end to the carriage 3; The cord is of suchlength en soarranged that it raises cutter 67, at the end of the forward stroke ofcarriage 3, a suliicient height to be engaged by the spring latch ortrigger 12, in which position it is held by the trigger during the rearward stroke of carriage 3 and a portion of the forward stroke. When thepoint of s ring 61 passes int-'0 a perforation in the lobe -web thecircuit of magnet l is closed at contact pieces 59 end 60 and thearmature carried by the trigger being attgectcd the cutter is re.leased. 'lhc'cuttcrb? being held in elevated position during therearward stroke of shoe 18, allows the shoe to pass freely over slot 68toward hopper 50. A cake of gum or other article to be wrapped havingbeen fed by plunger 15, upon the web and under springs 55 and 56 shoe18, as it moves to the rear, strikes the tree ends of webs 8 and 9 whichare held up by spring 57, folds them' around the forward edge and downon top iof the cake where theyare held by spring 68. The shoe I travelsover the cake until its heelor lower cake. 'As shoe 18 moves forward itdrags with been turned over it and that are clamped by of the it thecake together with the webs that have spring 68. During this forwardtrevc webs, a perforation in the label web is brougl t opposite thepoinflof Spllbgf 61, the contact pieces come together, magnet 1 isenergized and cutter 67 is instantly thrown down by its spring, the websbeing severed at the proper point, i. (a, midway between the lacls. Tofacilitate assembling the contact apparatus is madeudjustabllongitudinally oi the base plate. The mac line can not get outof time, so to out the wrapper across the label or fail to ragister theprinted label portion properly on the coke, because cutter 67 willonl ydescend when the pol nt of spring segues 61 meets a perforation, andwhen a perforation is over slot 66. The cutter may be of I anyappropriate character. As shown its edge is serrated, as also are theedges ol the slot 66. The term perforations (referring to the web) asused in the claims is intended to include equivalent apertures, slits,notches or other breaks in the continuity of the sur face of the web.The web severing means controlled by such perforations are shown aselectrical and are preferred for the reason that not only instantaneousaction of the cutter is eilected, but the part controlled by theperforations may be very light, have but slight pressure upon the weband small extent cl movement.

In order to prevent the webs from being carried forward out of positionwhen a take of gum is ushed out upon them, 'a stop 63 working t rough anaperture on the base late is mounted on a spring and adapted to bedepressed by plunger l5 and hold the waxed web 9 firmly while tho mikeis being pushed thereon.

It is unnecessary to describe or'show the remaining operations forfolding the wrapper over the article and discharging the wrapped packagefrom the machine.

The electric circuit may be arranged in any appropriate way. Asindicated spring 61, carrying contact piece 59, is insulated, andcontact 60 is in electrical connection. with the frame? Consequently oneterminal of the magnet-coil should be connected to spring 61 and theother should be connected to an insulated pieoewith which some movingpart of the frame contacts at such times as energization of the magnetis required.

I have shown in Fig. 1 part of the folding devices ldescribed andclaimed in my epplicetion Serial Number 253,517, liled April 3rd, 1905.Such folding devices form no part of the invention lierein claimcd andhave been shown in the drawing merely to illustrate one way in which thepaper web, or webs, may be drawn forward. v
